Lung cancer is a disease characterized by uncontrolled cell growth in tissues of the lung. If left untreated, this growth can spread beyond the lung in a process called metastasis into nearby tissue and, eventually, into other parts of the body, according to Wikipedia. The disease common among smokers predominantly leads to almost 1,370,000 deaths every year worldwide. We give you risks and symptoms associated with this form of cancer.

(Risks For Lung Cancer) Smoking: It is the biggest risk factor for lung cancer; causing 85 percent of all lung cancers. the chances of a smoker getting the disease is 10 to 30 times greater than that of a nonsmoker. Tobacco in all forms and smoking and chewing tobacco, are major risk factors for cancers of the mouth, throat, and lungs.

Occupational Hazards: The place you work, or the enviornment you are exposed to for a long time can be a source of lung cancer too. This includes secondhand tobacco smoke, asbestos, arsenic, radiation, and some chemicals. Dust and fumes from nickel, chromium, and other metals may also increase the risk of lung cancer.

Age: Though the condition is prevalent among older adults, it can occur in young people too. After age 40, the risk for developing lung cancer slowly increases every year.

Genetics: Some people have a genetic risk or predisposition for lung cancer. Anyone with a first-degree relative (parent, brother, sister) with lung cancer has a higher risk of developing lung cancer themselves.

Symptoms: Signs of lung cancer are often not apparent in the early stages. However it is better to identify lung cancer as early as possible. The most common early symptom of lung cancer is haemoptysis (coughing up blood).

Primary signs:

Hacking, persistent cough

Coughing up blood

Shortness of breath

Wheezing

Chest pain

Lost appetite

Lost weight

Recurring bronchitis or pneumonia

The above symptoms are also the symptoms of many other lung problems, so it is always advisable to see a physician to ascertain the cause.

Secondary signs:

Weakness

Difficulty swallowing

Changes in nails

Hoarse or raspy voice

High fever

Swelling of facial features

Lung cancer doesnt reveal itself until advanced stages; however, sometimes people exhibit signs early in the disease's development. It is imperative that the first notice of symptoms or concern sends you straight to the doctor. The sooner treatment is begun, the better. A cure is possible if caught early enough and, if not, then a better quality of life and more of it.

When lung cancer spreads to other parts of the body, organs and bones, it is referred to as 'metastasizing'. Signs and symptoms include:

Aching and sharp bone pain

Changes in the brain that exhibit themselves through weakness, numbness, dizziness, and seizure
